PRECAUTIONS
Precaution for Working Range at a Regular Dealership
INFOID:0000000009164364
CAUTION:
The service items unmentioned on this manual are recommended to be performed by a GT-R certified
NISSAN dealer. Because those service items require special equipment and a GT-R certified technical
staff who completed special training.
Precaution for Procedure without Cowl Top Cover
INFOID:0000000009162802
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009162803
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precautions Necessary for Steering Wheel Rotation After Battery Disconnection

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,
then disconnect both battery cables.
• After finishing work, confirm that all control unit connectors are connected properly, then re-connect
both battery cables.
• Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing
work. If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.
OPERATION PROCEDURE
1.
Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2.
Turn the ignition switch to ACC position.
(At this time, the steering lock will be released.)
3.
Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4.
Perform the necessary repair operation.
5.
When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)
6.
Perform self-diagnosis check of all control units using CONSULT.
Precaution for Battery Service
INFOID:0000000009162805
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Special Cautions to Ensure the Safe Disposal of Sodium-filled Exhaust Valves
INFOID:0000000009162806
Handling and disposal of sodium-filled exhaust valves requires spe-
cial care and consideration. Under conditions such as breakage with
subsequent contact with water, metal sodium which lines the inner
portion of exhaust valve will react violently, forming sodium hydrox-
ide and hydrogen which may result in an explosion. Sodium-filled
exhaust valve is identified on the top of its stem as shown in illustra-
tion.
DEALER DISPOSAL INSTRUCTIONS
CAUTION:
• Use approved shatter-resistant eye protection when performing this procedure.
• Perform this and all subsequent disposal work procedures in an open room, away from flammable
liquids. Keep a fire extinguisher, rated at least 10 ABC, in close proximity to the work area.
• Be sure to wear rubber gloves when performing the following operations.
• Make sure the resultant (high alkalinity) waste water does not contact your skin. If the waste water
does contact you, wash the contacted area immediately with large quantities of water.
• Dealers should check their respective state and local regulations concerning any chemical treatment
or waste water discharge permits which may be required to dispose of the resultant (high alkalinity)
waste water.
